VOICE MAIL/AUTO ATTENDANT INTEGRATION
This section focuses mainly on in–band integration.
Because of the increased popularity of voice mail and auto attendant use, DCS-816 includes many
programmable options to address this demand. The degree of integration that can be achieved depends on
the abilities of the voice mail/auto attendant (VM/AA) system as well as the telephone system.
This list details the capabilities provided by the DCS-816 for voice mail via in–band integration.
Hardware Provisions
The VM/AA system must be connected to single line circuits on any SLI port.
Each port is equipped with a dedicated DTMF receiver for detecting DTMF signalling from the VM/AA.
These ports also provide an instant break in loop current when the calling party hangs up. This is called a
disconnect signal.
Software Provisions
SCREENED OR UNSCREENED TRANSFER
There are no special codes needed to transfer a call. Simply hookflash, receive transfer dial tone and dial the
destination.
DIRECT IN LINES
Any C.O. call can be assigned to ring at an individual station or a station hunt group assigned to the VM/AA.
CALLS OR RECALLS TO THE OPERATOR
Dialling 0 will always result in a ringback signal. If the operator is busy, the call continues to ring in queue to
the operator. This prevents a caller from dialling 0 and reaching another mailbox because the operator is
busy.
MESSAGE WAITING
A VM/AA port can leave a message at any station or group of stations. The message waiting indication can
be set or cancelled at any station or station group with or without the stations ringing.
IN–BAND SIGNALLING
DCS-816 can be programmed to send the calling station’s extension number after the voice mail system
answers. These DTMF signals may include a leading digit to indicate the type of call and additional
information about the original caller. DTMF signals may also be substituted for call progress tones to speed
up voice mail call processing. This program allows call forwarding to a mailbox and bypassing of the main
greeting for automatic message retrieval. Blind transfers may be performed because the recall will be
correctly identified.
The effectiveness of this program depends on the ability of the voice mail system to make use
of this information.
STATION HUNT GROUP WITH OVERFLOW
Each station group can have an individual overflow destination with an individual overflow timer. The
overflow destination will ring whenever a call to the group is not answered. If the voice mail system
becomes inoperative, calls are automatically routed to the overflow destination.
